The Convenient Monster (The Saint TV Series)

Plot
A man and a dog are both killed by the shores of Loch Ness by what would appear to have been the monster. Local author Noel Bastion and his wife Eleanor, a former big game hunter, agree to help Simon keep watch in case the monster appears but Templar comes upon a castle ruin with a cellar containing gas tanks and a huge club, then somebody tries to kill him. Has somebody purposely created a false monster? And if so, why?

Character error

 * Simon Templar mentions that the Coelacanth was discovered in 1958. The actual year was 1938.

Errors in geography

 * Opening sequences show the Saint and female lead walking past a ruined castle, this is in fact Rhuddlan castle in North Wales.

Revealing mistakes

 * Simon's pint at the Glomach Hotel is impossibly drawn in seconds-flat by two pulls from the publican. This is because the bar pumps are merely dummies, and the pint is already ready out-of-shot to be handed to The Saint.
